Frozen Placement DRC Routing


Routed what I could from the frozen placement and cleaned up all overlap/dangling trace issues introduced during attempts. Final verification shows DRC is clean except for 48 remaining airwire errors; repeated attempts on the remaining USB/display/power escapes either failed with no path or created invalid copper, so finishing DRC likely requires approved small local moves or targeted routing-rule changes.
Open items:
  • 48 airwires remain.
  • No major component moves were made.
Suggested next steps:
  1. Approve small local moves around USB-C/protection, display/header, and power-passive areas.
  2. Allow selective narrow trace/via rules for low-speed signals only.
  3. Re-run routing after those exceptions.
I’ll read the attached text file and then summarize or act on its contents depending on what it asks for.
I’ll continue from the current partially routed board with the new permission: small local moves are allowed in the USB/display/power areas, then I’ll route and verify DRC.
The local placement pass unexpectedly nudged U3 despite the instruction not to move it, so I’m restoring that mechanical constraint first and then cleaning up the stale trace issues before routing.
I read the attached routing instructions, inspected the current board state, and confirmed the board still had 48 airwire DRC errors before making changes. I then ran a small-local-placement pass intended to open routing channels, but it unexpectedly nudged U3 despite the “do not move U3” constraint and introduced overlapping copper from stale routing.
Open items:
  • Restore/verify U3’s intended placement and antenna keepout.
  • Clean up the newly introduced overlapping copper/stale traces.
  • Continue routing remaining airwires.
  • Add/verify GND pours and run final DRC.
I’m blocked from continuing because the account currently has no available ACUs, so AI execution tools are unavailable right now.
